CARTRIDGE-CRIMPER.

Specification of Letters Patent.

Patented Jan. 14,1908.

Application filed uly 22. 1907. Serial No- 384.901.

To all whom it may concern:

Be it known that Gannon 'l. PHILLIPS, a citizen. of the United States,residing at Voluntown, in the county of New London and State ofConnecticut, has invented certain new and useful Improvements inCartridge- Lrimpcrs, of which the following a specification. p

This invention relates to cartridge crimpcrs and is designed to form aninternal annular crimp or bead in a paper shell for the purpose ofholding the wad in place. By pro ducing an annular crimp or head, incontradistinciion to folding inwardly theend of the shell, the shell maybe repeatedly used, asthe damage by repeated crimpings is very slight.

further object of the invention is to have the parts thereof assembledin compact relaiion and to enable the convenient manipulation thereof toquickly and successfully crimp a cartridge without requiring anyparticular degree of skill or experience.

With these and other obj sets in view, the present invention consists inthe combination and arrangen'ient of partsas will be hereinafter morefully described, shown in the acco mpanying drawings and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size and minor details may be made within thescope of the claims without departing 1' mm the spirit orsacrilicing anyof the ad vantages of this invention.

In the drawings, Figure 1 is a side elevation of a cartridge crimperembodying the features of the present invention. Fig; 2 is a top planview thereof. Fig. 3 is a front elevation. Fig. i is a longitudinalsectional view. Fig. 5 is a detail cross sectional view taken throughthe crimping elements. Fig. (3 is a side elevation of a cartridgecrimped-by the present device.

Like characters of reference indicate corresponding parts in each of theseveral figures of the drawings.

For the support of the working parts of the present invention, there isprovided a substantially U-shaped crimpingor supporting frame .1. thelower arm of which is pierced by a clmuping screw .2 provided at itslower end with a finger piece and at its upper end with a swiveled head3, whereby the frame may be clamped upon the edge of the table or othersupport.

Rising from rear and of the frame there is a tubular bearing 4, and uponthe top of the bearing is a pair 0 The working parts of the crimpingmechanism comprise a bifurcated tube 6 provided at its rear end with areduced cylindrical journal 7 mounted to rotate in the bar 4 andprovidedat its rear end with a concentric stud or projection 8 carryinga crank handle 9. By preference this crank handle is removable and mayhave a screw threaded connection with the stud as illustrated in thelongitudinal sectional view of the drawings. Located concentricallywithinthe tube 6 is a cylindrical center element 16, preferably tubular,and having its forward end reduced to provide a cylindrical flange 11.Loosely embracing the center element are a pair of crimping'jaws 12,each of which is substantially semi-circular in shape and provided uponits inner side with a substantially semi-cylindrical flange 13 designedto embrace the reduced or flanged portion 11 of the center element.Extendmg rearwardly from each jaw is a shank 14, and the two shanks arepivotally connected at their rear ends by means of a pivot pin 15passing through spaced cars 16 on the shanks. The rear end of the centerelement is provided with a perforate ear 17 received between the cars 16and pierced by the pivot pin. It will here be noted that the shanks 14work in the slotted or bifurcated portion spaced perforated ears 5. j

of the tube 6, and the pivot pin 15 passes through alined perforations18 in opposite sides of the tube. A suitable spring 19 acts upon theshanks of the jaws with a tendency to force the same outward..

The tube 6 is rotatably received withina sleeve 20 provided with a pairof diametrically-opposite -forwardly-projecting fingers 21 frictionallyengaging the respective shanks of the jaws. One end of the pivot pin 15projects externally of the tube and enga es a longitiulinal open-endedguideway or sot 22 in the inner wall of the sleeve, whereby the sleeveand the tube rotate together, and the latter is permitted to moveendwise in-. dependently of the tube, whereby the fingers 21 workingover the shanks of the jaws force the latter together when the sleevemoves outwardly, the jaws being spread apart by the influence of thespring when the sleeve is fed backward.

Supported upon the front part of the to of the frame 1 is a suitableclamp for hold ing the cartridge or shell during the crimping operation.This clamp com rises a pair of jaws 23 and 24 respective y )rovided withthe handles 25 and 26 normally forced apart by a spring 27.

Pivoted between the spaced ears 5 is a lever 28 having a depending.detent or projection 29 received within a spiral guideway 30 on thesleeve, the free end of the lever playing in a socket or guideway 31 inthe rear side of'the upper handle 25.

In practice, the paper shell or cartridge, such as shown at 32 in Fig. 4of the draw- .ings, is slid endwise through the cartridge holding clampwith its open end received within the clam ing mechanism between thecenter 10 and t e crimping jaws 12. When the handles of thecartridge-engaging clamp are pressed together so as to.clamp the jawssnugly upon the cartridge and hold the same, the lever 28 is' depresseduntil its detent or projection 29 engages the spiral guideway 30, andwhen the crank handle is operated the tube 6 will be rotated and thesleeve fed. forwardly. As the sleeve feeds forwardly,

the -crimping jaws are gradually pressed against t e shelland the latteris crimped by the jaw flanges 13 around the cylindrical 'flange 11 ofthe center 10. When the ham dles of the cartridge-holding clamp arereleased and swung apart, the lever 28 will be lifted with the handle25, thereby freeing the sleeve 20 to.longitudinalmovement,

whereupon the crim ing' -jaws will spring outward under the in uence ofthe spring so as to release them from the cartridge and permit of thelatter being withdrawn from the device with an internal annular crimp or.bead pressed therein.

"What is claimed is 1. A cartridge crimper com rising acartridge-holding clamp, rotatab e mechanism for en 'aging and crimpinga cartrid e held in the 0 amp, and means controlled by the clampforcontrolling the crimping action.

2. A cartridge crimper having a-cartridge holding clamp, a rotatable andradially movable crimping jaw, a feed sleeve embracing. and rotatablewith the jaw and ca able of endwise movement thereon to force t e sameinwardly, the sleeve being provided with avcated portions of the tube, aspring normally tending to se arate the jaws, a'center element embracedliiy the jaws, a pivot pin common to the center and the shanks of thejaws and piercing the tube one end oi" the pin projecting externally ofthe tube, a feed sleeve embracing the tube and having a longitudinalguideway receiving the projecting end of the pin, said sleeve havingportions cooperating with the jaws to force the latter inwardly when thesleeve is slid forward, and means to feed the sleeve endwise when thetube is rotated.

5. A cartridge crimper having a. cartridge holding clamp, a centerelement, a rotatable and radiall movable crimping jaw cooperating withthe center element, a feed sleeve embracing and rotatable with the jawand capable of endwise movement thereon to force the same inwardly, andmeans arran ed to feed the sleeve endwise under the in uence of therotary movement thereof.
